NEW YORK, N. Y., A CORPORATION OF DELAWARE VALVE j Application ledMarch 5,-.1929f- Serial No. 344,116.

My invention relates to valves. I have developed a valve which is quiet in operatiompermits the passage of liquid or oil, is sturdy in construction, simple to manufacture, and does not require adjustment.

after described, which, consequently, is of particular valuel for domestic refrigeration. However, the valve is obviously applicable to other uses. Y

The majority of valves at present used have u single closure member. This member usually, clicks on seating; My novel valve, which has a plurality of overlapping movable clo-V sure members of spring-like characteristic,

. doesznot click on seating.

The nature of the inventionand further ndvantageswill be apparent vfromthe following descriptiontaken in connection with the accompanying drawings, whereon:

Fig. 1 shows a valve in accordance with the present invention, and

Fig. 2 is a cross-sectional view on the line 2 2 of Fig. 1.

Reference character 10 designates a circu-v v lar port member. As the valve is applied to a refrigerating compressor this member is a p 4 flexible plates andineans for individually ksecuring said plates to the port ,member at iiXedplate at the upper end of the compresv s'or cylinder. 1n the center of the port meinber is a port 11 comprising two chambers on,

each side of the port member and three passages 12 connecting-the two chambers. The

flow of Huid through the valve is indicated by `an arrow. A projecting annular boss has the valve seat thereon. The valve seat Vis flat.

' lThe valve closure comprises three radial- `lyeXtending flexible, spring-like, flatplates A f 14, rfixed to the port member near the edge and free to move over the valve seat. Y

Plates 14 are heldin place by a relatively heavytop plate or guard memberV 15 and sorewsl. Top plate 15has a central circular kportion and three radially extendingfarins,

1200 apart, covering the plates 14. Screws 16 pass through holesin the arms of topplate 15 and through individualholes in `plates 14.

Top plate 15 serves to limit i'novement ofV plates 14. Washers 17 may be iise'dfunder the Between the .arms vof the topplate are downwardly extendingr lugs 18 whichhave a position outside the vcircular portions of plates 14 and limit sidewise movement `of theseUV f' plates about the pivots formed by screws 16.V

It will be noted thatholes 12 are radially in line with thearms of the top plate and with the extending portions of the plates 14.

While I. have'described the preferred formy of valve, it'vvill be.uiiderstood that variations are possible witliintlie spirit and scopeof the invention.

Having thus describediny invention, what l claim is:

1'. A valve `comprising-a port member having a port therein andavalvc closure for covering saidport comprising a plurality of flexible flat plates [having securing portions seciii'edto different parts of said port member and converging from the respective securing points toward the port and toward each other and having overlapping" portions adjacent said port.

2. yA valve comprising'a'circular port memj ber having a .port'therein centrally disposed and avalve closure for covering'said port comprisinga pluralityof radially extending n different points adjacent the edge of the port member and said pla-tes converging from the yrespective securing points andhaving overlapping portions adj acentsaid port.

Af lvalve comprising circular port member having a'port therein centrallydisposed and a. valve -'closure Vfor covering said port comprising. a pluralityof fiat flexible lplates extending radially, 120o apart, andy kcomprising a plurality'of flat fiexibler plates extending radially, 120O apart, and means for securing said plates and limiting movement thereof.

5. A valve comprising a port member having a port therein,'a valve closure for covering said port comprising a plurality of flexible members having overlapping portions adjacent the port, means to individually secure the plates at different points away from said port, said plates converging toward said port and means Vto limit movement of the flexible members away from the port and sidewise with respect to the port.

6. A valve comprising a port member having a port therein, a valve closure for Covering the port comprising a plurality of flexible members extending toward each other and having overlapping portions adjacent said Vport and being outwardly secured, a guard member over the plates having` extending arms, bolts passing through the arms and the plates and lugs on the guard members for limiting sidewisre movement of the flexible members.

7. A valve comprising a port member liaving a port therein, a valve closure for covermg said port comprising a plurality of radially extending flat flexible plates, a guard member over said plates secured to the port y member with the plates between the port member and arms on the guard member, lugs on the guard member for limiting sidewise movement of the plates and said port comprising a plurality of holes, one radially in line with each arm of the guard member.

8. A valve comprising a port member having a port therein, a valve closure for covering said port comprising a plurality of radially extending flat flexible plates havingV overlapping portions adjacent said port and being individually secured away from said port, a guard member over said plates and said port comprising a plurality of holes, one radially in line with each of said pla-tes.

9. A valve comprising a port member having a port therein, a valve closure for covering said port compiisinga plurality of radially extending flat flexible plates having overlapping portions adjacent said port and being individually secured away from said port, a guard member comprising a plurality Vsecured to the port member away from said port. v

ll. A valve comprising a circular port member having a port therein centrallyrdisposed and a valve closure for covering said CLYDE EDWARD PLOEGER.
